Constellation Energy Corporation (CEG) Q2 FY2026 8-K Filings and Company Events

Calpine acquisition, closed

January 7, 2026, acquisition of Calpine Corporation completed. Constellation completed the transactions contemplated by the Agreement and Plan of Merger dated January 10, 2025; Calpine was converted into Calpine LLC and became an indirect, wholly owned subsidiary. Merger consideration was 50,000,000 newly issued Constellation shares plus $4.50 billion in cash less company expenses; former Calpine stockholders received approximately 13.8% of Constellation's outstanding common stock. At closing Calpine remained the issuer of $1,400 million of 5.125% senior notes due 2028, $650 million of 4.625% senior notes due 2029, $850 million of 5.000% senior notes due 2031, $1,250 million of 4.500% senior secured notes due 2028 and $900 million of 3.750% senior secured notes due 2031, and subsidiaries CCFC and Geysers Power Company remained party to their term loan facilities.

(Accession 0001868275-26-000029)

March 31, 2026, 2026 Business and Earnings Outlook. Constellation initiated 2026 Adjusted Operating Earnings guidance of $11.00 – $12.00 per share, based on expected average diluted shares of 361 million; raised total available share repurchase authorization to $5.0 billion; identified $3.9 billion of growth capital expenditure; and reported that Moody's and S&P affirmed ratings at Baa1 and BBB+ following the Calpine close, with Calpine's own ratings raised to investment grade. Management framed a target of 20%+ Base EPS growth from 2026 to 2029. (Accession 0001868275-26-000045)

May 11, 2026, first quarter 2026 results. GAAP net income of $4.49 per share versus $0.38 a year earlier; Adjusted (non-GAAP) Operating Earnings of $2.74 per share versus $2.14. Full-year guidance of $11.00 – $12.00 per share affirmed. Operating revenues were $11,122 million against $6,788 million in the first quarter of 2025. Operational items included commissioning of the 105 MW Pastoria Solar Project, commercial operation of the 460 MW Pin Oak Creek Energy Center on April 30, and PUCT approval, subject to conditions, of the net metering application for a CyrusOne data center co-located at the Freestone site. (Accession 0001868275-26-000063)

August 6, 2026, second quarter 2026 results and guidance raise. GAAP net income of $1.42 per share, down from $2.67 a year earlier; Adjusted (non-GAAP) Operating Earnings of $2.55 per share, up from $1.91. Operating revenues were $7,504 million for the quarter and $18,626 million for the six months. Full-year Adjusted Operating Earnings guidance was raised to $11.50 – $12.50 per share from $11.00 – $12.00. Management attributed the adjusted-earnings increase to the addition of Calpine and favorable market and portfolio conditions, partially offset by unfavorable nuclear outages. The gap between the GAAP and adjusted figures is driven largely by a $340 million after-tax unrealized fair-value loss, $149 million of amortization of acquired commodity contracts and $84 million of Calpine merger and integration costs.

Concurrently Constellation purchased 2,000,000 of the offered shares from the underwriters at the underwriters' purchase price, for an aggregate of approximately $558.0 million, under its existing repurchase program, leaving approximately $3.5 billion of remaining authority. The offering and the share repurchase closed on June 2, 2026. (Accession 0001104659-26-069482)

The company describes this as the last asset sale required by the regulatory commitments attached to the Calpine acquisition. Closing is subject to Department of Justice approval and other customary conditions, and the company expects it to close by the end of 2026. This is a signed agreement, not a completed sale.
